Unity VFX Graph won't open after using it as subgraph.

Question

Description of problem

I'm using the Universal Render Pipeline (URP) and when I go to open one of my VFX graphs after adding it to another graph as a subgraph it suddenly won't let me open the subgraph and just gets stuck in an infinite loop going between "Collecting dependencies" and "Saving shaders" whenever I try.

Has anyone experienced this bug before? Any suggestions on where I can find log files to try and find out what's going on or suggestions on how I might fix it?

Already tried:

Duplicating the vfx graph and removing the old one, it fixes it til I re-add it as a subgraph then it breaks again.
Reimporting all sub graphs and the main graph.
Remaking the vfx graph that uses the broken ones as sub graphs.
Restarting Unity/my PC.
Reinstalling VFX graph package.
Looking for the problem in the Unity Editor logs.

Extra Info:
Unity version: 2021.1.12f1
Visual Effects Graph version: 11.0.0

I solved this issue by moving the main graph and subgraphs into the same folder. Seems like a bug that should be addressed though.

Do you know the way to reproduce this bug? I can report it or something, but I don't know how to reproduce this. Or do you have simple example that can be sent to Unity and does not violate any conditions in your work?

I will take some time tomorrow and try to make a project that I can submit that reproduces the issue.

Since i fixed it by having all graphs in the same folder I will try the main graph in one folder and the subgraphs in a different folder in a subfolder aswell. (MainFolder - > MainGraph) (SubFolder - > SubFolder2 - > Subgraphs)
